APPARATUS FOR COVERING FLEXIBLE cowuuus WITH RUBBERIN CEMENT OR LIQUID FORM.

SPECIFICATION forming part of Letters Patent No. 701,472, dated June 3, 1902. l Applieation filed June 7, 1901 Serial No. 63,523. (No modeld To all whom it may concern:

Be it known that 1, JOHN T. DICKEY, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New .Tersey, have invented certain new and useful Improvements in Apparatus for Covering Flexible Conduits with Rubberin Cement or Liquid Form or other Similar Elastic Liquids, of which the following is a specification.

This invention relatesto an improved apparatus for covering flexible conduits with rubber in liquid'form or similar elastic liquids; and it consists of an apparatus for coating, drying, and cleaning flexible conduits while they are moved from one roller to another. I attain these objects-by the mechanism illustrated in the accompanying drawings, in whicl1- Figure 1 is a side elevation of my new device. Fig. 2 is a longitudinalsection of same. Fig. 3 is a top view illustrating my new device. Fig. 4 is a horizontal section on line 4: 4 in Fig. 2. Fig. 5 is a section on line 5 5 in Fig. 2. Figs. 6, '7, and S are a side, front, and top view, respectively, of an adjustable coating-controlling device. Figs. 9 and 10 are the same provided with a clamp regulated by a set-screw.

Similarletters refer to similar parts throughout the several views The flanged cylinder b, with its shaft and pulleyj, is supported by the standards 1).. 19. Around said cylinder Z) is stored the flexible conduit to be covered wit-l1 rubber compound.

The coating apparatus 0 consists of a vessel a, with its standards a a. One side g, vertically extending, has an opening to which a hollow conical cylinder his fitted, the bearer of a stationary or adjustable pipe t, controlling and spreading the rubber compound over the surface of said flexible conduit. A rod d, extending across the vessel a, is bearing two flat arms 6 c, in which a guide-rollerfis journaled.

Thedrying apparatus B consists of a table orplateK,itslegs orstandards KK. Asteamcoil m, secured to the top of the former, is incased by perforated sheet metal n. Brackets r '1", extending from said table or plate K, are bearing the guide-rollers 0 o. A cover 7', provided with slides s s, will inclose said. parts, leaving ample space for an endless belt 0, of

canvas and rubber, revolved by two flanged cylinders z :1, one provided with a driving-pulley Whereas below the other a friction-roller z is journ aled to the supporting-standards 2 2' The endless belt c.will rest on the guide-rollers 0 o duringits passage over the steam-coil m, a precaution taken to steady the movement of the belt and to prevent the same from coming too near the heating-coil.

The cleaning apparatus D consists of a vessel it, its standards'qfl, arms extending from upper part, in which the guide-rollers u are journaled same as the roller 10, located insidefof said vessel a, and a pair of brush-rollOIS U v, setin rotary motion by their pulleys iii.

The collecting-roller A consists of a flanged cylinder 1), its shaft and pulleyj supported by the standards Z) I). Said roller will serve to collect the flexible conduit after being coated, dryed, and cleaned.

The coating-controlling device consists of a sleeve 1 with an extending flat metal piece bent to the shape of a cylinder corresponding in width with the flexible conduit to be guided through. Aclamp with a set-screw, may be adapted to keep the so=forIIned cylinder in shape. (All shown in Figs. 6 to 10.),

By myimproved apparatus flexible conduits can be covered with rubber or other suitable material in a very quick and effective manner.

The flexible conduit being guided through the coatingpan partially filled With rubber in liquid form or similar elastic liquid will be coated by said material, its thickness being regulated by the spreading-tube secured to. the conical outlet of said pan when moved toward the drying apparatus, through which it is guided by the endless belt, secured to the former by any desired fastening device. When reaching the cleaning apparatus, the flexible conduit will be sufficiently dry and hard to permit a cleaning or brushing, whereafter the flexible conduit being ready for use will be guided tothe collecting-roller.

What I claim as my invention, and desire to secure by Letters Patent, is-'- 1. In an apparatus for covering flexible conduits with rubber in cement or liquid form or other similar elastic liquids,a coat-ing pan consisting of a vessel supported by standards, a guide-roller journaled to arms secured to a rod extending across said vessel, which has one side extending, perforated, a hollow cylinder partially conical, partially straight provided with two slots or eyes, secured over said perforation for the purpose specified.

2. In an apparatus for covering flexible conduits with rubber in cement or liquid form or other similar elastic liquids the combination of a coating-pan, a vessel supported by standards, a guide-roller journaled to arms secured to a rod extending across said vessel, having one side extending, perforated, a hollow cylinder partially conical, partially straight the bearer of two slots or eyes, secured over said perforation, with a spreading device consisting of a tube or pipe partially slit open intersected by a cross-cut, forming two laps, bent to a tube, its diameter regulated by a round clamp and its bolt, said pipe bearing two arms having their ends shaped to a hook, all substantially as set forth.

3. In an apparatus fol-covering flexible conduits with rubber in cement or liquid form or other similar elastic liquids, a drying-pan consisting of a plate supported by standards, a steam-coil secured to the upper face of said plate, incased by perforated sheet metal, brackets extending from said platenear longitudinal edges, in which are journaled guiderollers, a cover having slides on both of its ends, which incases said apparatus, all substantially as set forth.

4. The combination in an apparatus for covering flexible conduits with rubber in cement or'liquid form or other elastic liquids of a drying-pan, its plate supported by standards, a steam-coil secured to upper face of said plate, incased by perforated sheet metal, brackets extending from said plate near longitudinal edges in which guide-rollers are journaled, a cover having slides on both of its ends which incases said apparatus; with an endless belt supported by flanged rollers, journaled to brackets, a driving-pulley secured to shaft of one of said rollers, all substantially as described.

5. In an apparatus for covering flexible conduits with rubber in cement or liquid form or other similar elastic liquids a cleaning-pan consisting of a vessel provided with stand ards, guide and brush rollers extending across said vessel, the brush-bearing rollers rotated in same direction by means of driving-pulleys secured to their shafts, all substantially as specified.

6. An apparatus for covering flexible conduits with rubber in liquid form or similar elastic liquids consisting of a coating-pan, having a vessel supported by standards, a guide-roller journaled to arms secured to a rod extending across said vessel, having one side extending, perforated, a partially straight, partially conical cylinder fitted to said perforation, two eyes secured to the former; a spreading device consisting of a pipe, partially slit open, intersected by a cross-cut forming two laps, bent to a tube, its diameter regulated bya round clamp and its bolt, the straight portion ofthe adjustable pipe fitted to the same portion of the stationary, hook-shaped arms extending from the former fitted in the eyes located on the con? ical portion of the latter; a drying-pan consisting of a plate supported by standards, a steam-coil secured to upper face of said plate, incased by perforated sheet metal, brackets extending from former near its longitudinal edges in which guide-rollers are journaled, a cover with slides incasing said apparatus, an endless belt supported by rollers and its standards guiding the material already coated through the drying-pan; a cleaning-pan consisting of a vessel, its standards, guide-rollers and brush-rollers extending across said vessel the latter rotating in same direction by means of driving-pulleys; flanged rollers placed one in front of the coating-pan and one in the rear of the cleaning-pan, for supporting the conduit before and after the operation, and pulleys secured to the shafts thereof, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
